This is an undervolt test version of my new StupidFast Kernel v1.2.3. This is a TEST release (NO VOODOO). This kernel aims to be fast, compatible, stable, and have good battery life. It is based on my StupidFast v1.0.36.
Code:
Changes since 1.2.2:
Fix for the 0.5-1.0 second pause/lag opening apps/drawer
Scheduling Tweaks
I/O Tweaks
Changes since 1.1.23:
Stock 1ghz @ 1225mV
Changes since 1.1.14:
Tweaked minfree settings
tweaked io scheduler
more compiler flags for cortex/hummingbird cpu
tweaked wifi scan interval to help with battery life
Changes since 1.0.36:
removed custom boot animation to trim size.
using kernel jhash3 instead of jhash2.
optimized compiler flags for the hummingbird cpu.
changed some kernel scheduling timings.
BLN disabled by default (configurable with [url=http://forum.xda-developers.com/showthread.php?t=823922]this app[/url])
You will see that the custom boot animation was removed. It's okay. If you already have v1.0.36, 1.1.4 or 1.1.23 installed on your phone, the animation will stay. If you're new to my kernels with v1.2.3, your old boot animation will be there.
I'm not seeing any lag on the phone. Gallery opens pretty much instantly. Settings->Applications->Manage opens pretty much instantly. Launcher Pro+ pretty much instantly appears when the phone starts up.
Testers could NOT find any audio problems with this kernel using the media player in JT's Clean ROM. I've tested Youtube and Pandora and have had no audio issues. Also, we couldn't find any issues with USB mount/unmount, settings changes, etc.
As always, if you find a bug or what you think might be a bug, let me know. This is NOT the final stable release of the 1.2 kernel. Stay tuned to #samsung-fascinate on FreeNode or @geeknik on Twitter!

Thanks to saps, jt1134 my beta testers and the kind folks that donated cash to the cause! Keep fighting the good fight!
sweet. dowlloading now.
Downloading also.
I like your kernels, but I just noticed I am getting a super weird output in ADB when I try using that. I also have superdark ROM so it could be either one.
Ok, I just rebooted and checked again and all is running fine with 1.2.2 in recovery, but not in running android system, must mean its the rom.
Downloading now.. went with full full wipe with jts clean, and still getting popping, on asop player, double twist, pandora
Besides the battery life which is supposed to be increased, is there any other benefit to UV ???? Longer processor life, runs cooler, etc.
What are the drawbacks, if any ???? Does performance take a big hit, etc.
I'm asking more in general terms. Obviously I will observe first hand with this kernel, which I'm downloading now.

In theory, as I know computer not cell phone, UV will allow it to run cooler, which does mean last longer (but is that really a problem?) and use less juice while still being as fast as before. If it runs stable you will not see a performance hit and it will better with the battery. It will just freeze your phone if its too low and requires more juice, really no harm can be done, overvolting is more dangerous as that burns up cpus, but you overvolt to make the higher frequency stable. Simple overclocking principals apply, you want the lowest voltage for your cpu frequency.

are you upping the CPU to 200mhz to run those? I am doing that and its just fine, although I never had a popping problem at 100mhz either. I just set the min to 200 because that cleans up a little bit of the lag too.
Possibly related, every once and a while my phone will just decide to press a soft key on its own, what is that? (that causes a slight skip in the music when I am playing it)

see if listening to it while hooked to power recreates the problem... i noticed for me atleast its only when plugged in...
I have it up to USB and its not skipping or popping right now, I am also using mixzing
v1.2.2 is the least fastest of all the geeknik kernels for me. There is 1 almost 2 second pause loading and exiting apps unless it was already in memory.
Still faster then everyone elses kernel. And so far battery life looks to be way better on this one but I haven't had it long enough to say for sure.
Nothing has changed on my audio popping issues so I am still using SetCPU at 200min still. I am short 6 hours of battery life like this by my best guestimate... which isn't a big concern for me- just reporting for those who need to make it thru a day without a charger nearby.
Never had any FC's with USB.

And a thank you to geeknik for all your efforts! love how your pumping these out!
Kernal runs great! No unwanted sounds from the stock music player in jt's rom. USB works just fine. Thanks for your hard work!
are you using setcpu? if so that helped me fix it bumping min to 200... any one else having the problem might try that...
Interestingly enough, this kernel does seem a touch slower than the 1.2.23 regular voltage kernel. Hangs just the slightest bit when firing up and exiting dolphin browser and xda app. Still, appears to be MUCH better with battery life, as the previous geeknik kernels were ravaging my battery.
Definite progress but not quite perfect imho. Still thanks for all your work geeknik, you're killing it with these.
Also fyi, running custom blackhole, with sns and lp

This kernel is running fairly smooth, like the other 2. I can deal with the extra 0.5 second delay when first opening an app, as long as BLN is optional and battery life is extended. Thank you very much for taking the time to come up with these kernels for us. Other kernel providers tend to make their products less accessible for us XDA users, but you take the stress out of the search. Thank you again.

The uv kernel is a winner of course. I test these kernels for geeknik before he throws them up for the masses. Not just running quadrant [although I do that too] but going thru the real phone stuff itself. The manage applications load, replacing new dock shortcuts, gallery, apps and stuff everything we actually want to see improve with.
I for one never had battery issues with previous stupidfast kernels but I know some did, same this music crackling. It seems to me most of you that do are either running blackhold or deodexed rom though and quite humbly I'd look their for your culprit moreso than the kernel. If there was a music skipping issue from the kernel itself it would manifest itself across the boards but it doesnt.
Anyway, battery life is going to be stellar trust me, under light-moderate use Im only using like 2% per hour here swyping 8-10 texts per hour here, very good indeed
Hey Saps- I see ya on all the forums and your contributions have really helped me out...
That being said I keep seeing an overlook of real world usage in these testings. Can you guys test beyond stock apps? I mean checking stock should be the first thing you do obviously but how many people use the stock music player or the stock browser, etc? I am betting most the people that have the knowledge enough to test these kernels and ROMs aren't using stock functionality and apps.
Please test this kernel with the PowerAMP or Music PlayerPro music apps before writing off the issue.
Use Dolphin to check the internet, etc. Use K-9 to check email, etc.. ya know- use the popular apps during testing also if you could?
Audio cracking, FC's with the USB settings, and I even heard mention of live wallpapers having issues. These reports coming from 3 reported different ROMs.
How are you missing this?
I myself have had great success with battery life on the Stupid Fast kernels. Better then stock kernel for sure. But I've been having to run my battery faster by using my workaround to avoid the music crackling.

hi just wanted to ask if there is a ROM there that is as close as the original ROM of the samsung galaxy s II in terms of apps and looks but is tweaked for better battery perfomance?
cause my dad bought a SGSII almost a week now, and we only get about 5-6 hrs of it using only it. already did about 4 charge cycles. (4 only cause most of the time the GSII is off, my dad's getting a hang it yet)
config:
- stock android 2.3.3
- 3g auto
- auto backlight (but we are inside a mall so the backlight is isn't that bright & have strong signal)
- auto sync is off
- background data is on
- haptic feedback is off
- audible selection is off
- fast dormancy is off
- power saving mode is on
- juice defender app in balanced setting
apps running:
-skype
-messenger
it drains a LOT even in standby a lot more when using it (browsing, not yet chatting). my hd2 is much more efficient knowing it is not a native android smartphone...
is there a tweaked battery efficient rom there that is as close or at least still looks as the stock?
You can do three things,
1- Install Better Battery Stats and see under 'Partial Wakelocks' to see whats running on background.
2- Stay on Stock ROM and flash a kernel which allows Voltage tweaks and install SetCPU and Undervolt CPU. Ninphetamine 2.1.3 is such a kernel.
3- If thats too complicated for you, then flash an Undervolted kernel, like SpeedMod.
I won't advise you to change to a Custom ROM for battery backup betterment. But doing the above processes will certainly save some.

thanks for the quick reply, so custom kernels work with the stock rom...i thought it won't. i'm not that familiar yet with native androids cause in HD2 most of the undervolted kernels there are already built in the roms so i don't change it that much now with the NAND builds....but anyway, i'll try for the mean time # 1 & 3....i'm not that into that #2 tweaks yet in a phone that is not really mine....
It is proven that Stock ROM's with custom Kernels have sweet battery life. As with Stock ROM's they haven't tweaked anything, it's just stock and you flash what YOU want, whereas a custom ROM you're getting things you dont infact need.
I keep going back and forth from Custom ROM's to Stock ROM's.
Hi
I would also recommend looking at SicOpat's ROM (http://forum.xda-developers.com/showthread.php?t=1183774)
This is essentially a stock, rooted ROM with a custom kernel and I find it exceptionally good.
The other thing I would recommend then is to install Titanium Backup and freeze/uninstall a lot of the Samsung apps - WiFi Sharing, software update, *hub stuff. Removing these has a very positive impact on battery life.
Hope this helps.

I have also been troubleshooting poor battery life on my phone. I used to lose 10-15% an hour just idling. I reflashed Stock KH3 with the KH3 CF-ROOT kernel and reinstalled a few things (twitter, yahoo messenger, google voice, and some apps that don't sync data). Currently I had 18hrs now with 60% left. MUCH better. A lot of the time the phone was idle but I did listen to music, play some games, and browse the internet/chat, use wifi a bit. Phone only lost like 4-6% overnight. (sorry I don't have hard figures but I didn't document any of it on paper). I'm trying to find out what was killing my battery so I am installing things little by little but I would definitely recommend stock KH3. Seems great so far.
I think your problem lies with the wifi-sharing battery bug. I hear this is updated in newer roms. This was the biggest battery hog on my phone, but after noticing it, my battery life is excellent now.
When Wifi is turned on/off this erroneous process starts in the background called "Wifi-Sharing". It hides and drains your battery at a VERY fast rate. The remedy is simply to "Force Stop" this process after you use Wifi.
Let us know if that helps.
You could root the phone and install Titanium to freeze this process permanently.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
sorry for the wrong forum i got messed up in opening a lot of samsung galaxy sII threads....
i dont see the "wifi sharing" in my dad's GSII when we used it. and as with kies, i think JKG2 firmware is the latest, so i assume that the wifi sharing bug has been fixed there, yes?
i know it would consume a lot since the GSII has a big "engine" but i didn't expect it to eat a lot even on standby with only YM and SKype messengers running in the background.
i'm still observing it. i'm still running stock.
EDIT: i just used wifi to download an app then when look for running apps, i saw "wifi-sharing" is running but i didn't even turned it on
i just flashed Speedmod T38 kernel (it seemed less complicated to use ) now observing if my dad's SGSII gets better
I'm a new Galaxy S II (and new Android) user, and am a bit disappointed in the battery life of my new phone. It was running down extremely quickly yesterday, only lasting about 12 hours with relatively normal use (sending half a dozen texts, downloading 2 apps, checking Facebook and Twitter once an hour or so for a couple of minutes throughout the day). I allowed the phone to discharge completely and charged it fully last night, but this morning nothing seems to have improved. I burned up 10% of the battery in half an hour sending 2 texts, checking my emails, Facebook and Twitter and downloading and trying out a couple of apps.
I'm anxious to know if there's a bit of a burn-in time with the battery on this thing - does it get better after a few charges? I see a lot of people saying they can have the phone on for a few days in some cases, but that's definitely not my experience thus far.
I've installed JuiceDefender (balanced profile), AutoKiller Memory and Advanced Task Killer to try to sort things out but none of them seem to having too much effect and to be quite honest I'd rather not have to compromise my experience by running a number of apps like this to try to extend my battery life at all (nor do I want to have to turn the brightness right down to an unusable level, or set black wallpapers for example).
Does anyone have any real advice on this? I'm starting to think that switching ROMs might be worthwhile? I see that the leaked 2.3.4 ROM seems to have better battery life - is this correct? I'm a bit reluctant to switch to any other unofficial ROMs as there are so many I wouldn't know where to start. It seems they all make a lot of changes but I'd want to keep as close to the stock feel as possible, just with better battery life.
no one uses stock roms/kernels nowadays. u should flash a custom rom or kernel since they provided optimizations to batt life.

It is argued that task killers and memory killers will only make the problem worse. Juice Defender might be useful if you are using it for scheduling sync and turning WI-FI off when the screen is off, but this feature is only present in the Ultimate edition and you can turn off sync and WI-FI manually if you want. Also beware of rogue apps which are syncing all the time. It is normally the main reason of poor battery life.
Other reason, is that whereas powerful tech specs for phones were rapidly developed, battery technology didn't followed the pace. Our simply batteries cannot cope with our beasts.
Also, there is a thing that it's called "new phone battery blues" which is described as poor battery life due to excessive use of a new powerful toy. After you use your phone normally, for the purposes that normally people use a phone, your battery life will became better.
That said, personally I have a spare battery and a spare charger, and when the battery being used is low, I replace it with the charged one. Sometimes it is necessary, sometimes not.

They also have a tendency to look very tacky I think though. I think Samsung's skin and widgets are pretty nice and don't care too much for the mods I see in the screens of most ROMs. I'm really looking for something very similar to stock, except with better battery life if there are any suggestions? That's why I was thinking of just jumping to the leaked 2.3.4 if it had any noticeable impact on battery life...
Try using better battery stats, link in my sig, to see if you have any wakelocks, the thread has a good howto on using it.
The biggest thing that uses the battery on this phone is the screen, you will get between 4 and 6 hours of screen on time depending on usage and screen brightness.

Fair point - not all of the roms are everyone's cup of tea. My advice, as a starting point is to flash the stock XXKH3 variant for your area, and then flash a custom kernel, such as Ninphetamine's or Hardcore's Speedmod. This will greatly help with battery life, and also give you the ability (via root access) to use Titanium Backup to freeze apps and services you're not using, which is often the major cause of battery drain through 'wakelocks'; apps that prevent your phone from entering Deep Sleep, or continuously wake it up.
Update to the latest version in your area, uninstall those task killers and whatnot or do a factory reset, install the apps that you are going to use normally like facebook twitter and install better battery stats, decrease brightness to your most tolerable level.
use the phone normally and when the battery is low, use the tool provided in android to check if your phone is sleeping when the screen is OFF, if you are having wakelocks, then use better battery stats to find which apps are causing the wake locks.
No need to install battery management apps, or task killers or memory optimization apps (or as custom rom as yet), that would only compound you problem which may be a very small one to begin with
Thanks for the help so far guys. I've installed XXKH3 and flashed hardcore's Speedmod kernel, and am just getting things set back up the way I like them again. I'm going to uninstall the battery saving apps for now and see how the battery lasts the next couple days.
I'll install Better Battery Stats and keep an eye on any wakelocks too.
Thanks for pointing me in the right direction - it was all very simple and quick to get set up; the sheer number of kernels, ROMs, etc. is all a little overwhelming to me right now, being new to Android!

wow, good for you
I used HTC Desire before this device, and the roms on there actually hindered battery life, even with all the fancy underclocking, so I am betting, without even attempting to brick my phone, that they are just as overhyped on this phone too.
I get two to three days out of my phone, using it as a PHONE. I can send and receive emails and texts all day, along with phone calls and the occasional browsing and still get at least two days before it dies. I turn off data when I dont want it and stick it in 2G mode and it dares me to kill the battery.
Just let usage settle down and it's fine

That is wrong. I used to have a UGKG2 ROM and since I upgraded to XXKH3, the battery is MUCH better while the GPS pinpoints in less than 3 seconds with a 5meters accuracy.
I just installed the new Siyah 3.2b1 kernel to run my ShoStock 2.2.2 ROM last night and everything was working fine. I didn't make many changes other than switching the governor to lulzactive and the i/o scheduler to noop.
It was running fine over night (lost 0% battery).
Then today after I used the phone for a few minutes the battery seemed to drain a little quicker. I know its too early to complain about battery life but I decided to investigate. When I checked cpuSpy it showed that all of the frequencies were barely used (mostly spent in deep sleep over night) but the 1200 mhz frequency was used most after that (significantly more than the others). When I went back into voltage control (same thing with setcpu) I noticed that it seemed to be stuck at 1200 mhz. The only thing that fixed it was changing the governor.
Does anyone have any ideas on whats causing this and how to fix it (I had great battery performance on lulzactive before so would like to use it again)?
Just try clearing app data rebooting and reinstalling the app. That problem has happened to me every once in a blue moon and that fixed it for me.

Thanks, I'll try reinstalling the kernel.
Which app are you referring to? because I had this problem no matter which app I used to change the governor (Extweaks, voltage control, setcpu).

My first post here. I am total noob. I rooted and installed the newest ShoStock2 on my at&t galaxy s2. Everything works perfectly. I couldn't be happier. I also went bought the setCPU for overclocking it. That too seem to be working fine.
My question is. I didn't set up any voltage requirements. The only thing I did was to set it to 1600 MHZ and 200 min and change the governor on the bottom to Lulzcrative. Will this work? Do I need to actually do something with the voltage? am I really on 1600 right now? I cannot tell.
I ran a quad test (I now it is meaningless in real world) it came 2818 yesterday. I ran it again this morning ..... It froze and took my battery from 45 to 9 in less than 3 mins!!!!!! The phone got really hot. I took out the battery right of way. The battery life showed 23 percent this time.
I got little afraid of the quadrant testing ... The phone seems to run good without that but I am not sure if it is set up how it is suppose to.
Could someone help me out please? I tried reading the forums and that is where I got the idea in the first place to overclock it.
So to summarize it, I guess phone is fine right now but I am not sure if I set up setcpu out properly.
I am on the newest shostock2. I have galaxy s2 on att. I am pretty good with computers and phones but not sure about voltage and other problems with relating to setCPU.
Thank you advance for helping me out.

Lots of questions there. Phone overclocking is the same and at the same time different than PC overclocking. I too bought SetCPU and due to bugs and problems have completely abandoned it. Honestly with the exception of running an epeen benchmark there is little incentive to overclock. Find a newer Kernel (I use NEAK which has no overclocking ability) and install it, performance is stellar. You really have to ask yourself, is my phone slow enough that I need more CPU power to make it faster?
To see what time your CPU is spending at a given clock speed, download CPUSpyhttps://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&feature=nav_result#?t=W251bGwsMSwyLDNd, you will be surprised to see your phone spend very little time at it's max clockspeed.
Due to the immaturity of the fab process for our CPU's (well SoC), what is a stable overclock for one person might not even load for another. These CPU's are not like an Intel Sandy Bridge, with 1Ghz of free overclocking, nearly guaranteed. You can certainly play with voltages to try and attain a higher overclock, but at the expense of CPU lifetime, as well as battery.
Additionally, it takes a new Kernel 3 or so full charge, discharge cycles on a phone to really 'settle in' and 'learn' a particular phones battery, while yours got hot, which to me indicates an endless loop of some kind running in the background.
My advice would be as follows: Choose a ROM you like, feel free to play with different Kernels, again, I use NEAK, which does not work for some folks, or crashes or whatever. Give it several days to 'settle in' and if your still not happy with performance or have stability problems, try a different governor/scheduler. You really need to establish a good, solid baseline of your phones performance and make small changes and give them long enough to establish any changes to your phones overall stability. Basically running cowboy through your phone and making changes will have a negative overall outcome. Make small, documented changes, test and see what overall effect this has to your phone's stability and battery life, and make another change.

I just installed the new Siyah 3.2b1 kernel to run my ShoStock 2.2.2 ROM last night and everything was working fine. I didn't make many changes other than switching the governor to lulzactive and the i/o scheduler to noop.
It was running fine over night (lost 0% battery).
Then today after I used the phone for a few minutes the battery seemed to drain a little quicker. I know its too early to complain about battery life but I decided to investigate. When I checked cpuSpy it showed that all of the frequencies were barely used (mostly spent in deep sleep over night) but the 1200 mhz frequency was used most after that (significantly more than the others). When I went back into voltage control (same thing with setcpu) I noticed that it seemed to be stuck at 1200 mhz. The only thing that fixed it was changing the governor.
Does anyone have any ideas on whats causing this and how to fix it (I had great battery performance on lulzactive before so would like to use it again)?

Lulz has known problem in 3.2b2-1
Gokhan has fixed it in 3.2b2 - 2
Wait for ktoonsez to update it for us

Thank you so much for the information. Could I simply uninstall the setcpu and go back to normal? Simply reflash the rom and/or kernel? I really like shostock2 with the cherry picker kernel for now. I want to give them a week of try to make my mind. Before the setcpu I think.I was better off
Thanks for the help by the way. I appreciate it.
Thanks for the update about the new siyah kernel. Glad it wasn't just me with the issue. I was going to post this question in the siyah thread but am new to the site so didn't have permission so thanks for finding me all the way over here

Lol what exactly have u heard? If it was causing problems it would get pulled. The only thing I can foresee happening is someone flashing it and then not flashing a kernel or something. Which would be user error.

I'm just going off what I've seen in the Siyah/NEAK threads. Most of the lock-ups/random reboots I've heard people having had used the cleaning script. Either that or its just coincidence.
I may be wrong but I think that using the kernel cleaning script actually solved most of the lockups. Perhaps I misunderstood the threads.

Hmm, well I've just manually wiped cache and dalvik and have never had problems between roms/kernels.

I have been struggling with trying to figure out if the battery life I am seeing is what my Atrix is really capable of. I am occasionally a heavy user, but on weekends I am a very light user. I'll start at 8am with 100% and be almost dead at 6-8pm. I have searched around and seen other Atrix users with 24 hours of battery life and even if I tried my hardest to not use my phone I wouldn't get those kind of numbers. I feel fairly confident in saying i scoured search results and tried everything i could find to extend battery life.
Am I doing something wrong?
Is there something I can do to help?
I know it's been asked before, but I am hoping to get some current answers for this question: what kind of battery life numbers are you getting on your Atrix? Which rom are you using?
Atrix 4G running CM7 RC3. If the answer is "keep it charged as often as possible", it is what it is. It would be great to find an answer to why battery life is so much shorter than others though! Many thanks in advance.
Just noticed CM7.2 stable was released, upgrading to that now to see if battery life improves. Might try a full wipe to see if battery life is better without email, syncs, etc. etc. if the upgrade doesn't help.
i would recommend getting cpu spy and also download and install as a zip 'blue sleep fix' (blue sleep zip can be found in the CM7 thread). This has greatly improved my battery life.

Which kernel? Flash Faux 1.0GHz and undervolt across the board by -50mv. Instant battery life!
Also, use ROM Manager or equivalent to stop all non essential apps from starting on boot.

There are 2 cpu spy apps on the market, can you let me know which one to use? Bluesleep fix found and downloading now.

Flashed Faux 1.0 no problem. I do not know how to undervolt so I will search around and see if i can find something on it. Ill try stopping some startup apps too. Thanks for the suggestions all! Keep them coming!

Test your settings for a few days. If the phone stays stable THEN you set at boot.
Big thanks to everyone! Battery life has improved a ton (see picts)! It was hard finding the blue sleep fix, here it is for others to easily find: http://forum.xda-developers.com/showpost.php?p=25437046&postcount=436

Err, that is not good battery life at all bro. I can tell you barely used the phone. Atrix should be able to provide up to 2 days standby time...
I wouldn't undervolt either, I read on these forums that the battery gained from undervolting barely makes a difference

You should turn wifi off when not in use, that will save battery life.
Badass battery will let you know how you spend your battery by % and let you know which app takes the most battery. (Lets you get a really readable easily understandable battery read out.)
I can help you get even better battery if you use this app and give me some numbers (it has a share via gmail/etc)

turning off wifi is not going to help him that much. I leave my wifi on all the time no problems, make 2 days light usage no problem.
More likely he's got some apps running around in the background. I suggest he pick through what he's got installed and start turning off the things that like to sync all the time in the background.
I think step number 1 would be to install a non-stock ROM and startover fresh.
Blur-based ROMs (Nottachtrix was really good) then the faux123 kernel then slowly start installing the apps he likes to use and monitor battery life. It might take a month but he's definitely got an offender here or there causing these problems.
also install Juice Defender. My mom's Galaxy S2 was having tons of problems with battery life even though she wasn't using it at all, 60% battery life at 3pm without using it at all, installed that and immediately helped her a lot, like 80% by 3pm WITH use.
Also, clear your dalvik cache. After installing lots of stuff and not using it, it just fills up with sometimes poorly written code. Clearing it always makes phone faster in my experience.

Strangely, I keep setting wifi to turn off when the screen is off...but it keeps resetting itself. I wonder if I found a bug?

I think this is what I will do today! I'll do a nandroid backup, and try Nottachtrix with no extra stuff installed or setup. I will report back! I appreciate all the help to get my phone performing where it should be.
Just wanted to report in. I tried a clean ROM as stated in my previous post with no luck. I just couldn't get past the battery life I was getting with cyanogenmod WITH all of the apps and syncs enabled. Should I try another ROM maybe?
Maybe your battery is just a bit old? After ~2 years, you can expect that battery life drops dramatically. if you are a heavy user this might happen earlier. Maybe check with the battery of a friend of yours whether it's a software or a hardware issue
Nvmd
You could be right, the battery might be dying.
I was on vacation the past few days so I got the opportunity to not use my phone most of the day (job requires me to use the phone a lot). The battery lasted about 12 hours and looked like it had about 4 hours left. So maybe I am expecting too much, but I'm not trolling...no.
If you aren't going to be helpful, go somewhere else. You could have said "Your phone screen was on for probably longer periods than the average user and that's why you can't hit longer hours". Based on your previous comments, I shouldn't expect much from you though.
Many thanks to all who are helping me. You're all awesome.

11-12 hours.
I also have 11-12 hours with 1 charge. And it is not enough for me. I use only Whatsapp ( a lot usage ), a little bit browsing, 20-30 minutes phone calls. These are all. And 11-12 hours is sooo bad for them i guess.
I have an "suspend linux process" drainage issue. Maybe because of it, I'm getting this result.
How can I extend my battery life. PLEASE Help!
